CAMPAIGN: LACK OF ADEQUATE SERVICE OR MAINTENANCE

Subject: Lack of Adequate Service or Maintenance

Models: 1985-88 Pontiac Fiero Models with 2.8L V6 Engines (RPO L44)

TO: ALL GENERAL MOTORS DEALERS

General Motors of Canada has determined that a defect which relates to motor vehicle safety exists in 1985-88 Pontiac Fiero model vehicles with 2.BL V6 engines (RPO L44).

An interaction of the engine compartment environment in 1985-88 Pontiac Fieros and maintenance or service related factors results in the potential for engine compartment fires.

If combustible materials come in contact with the exhaust manifold, an engine compartment fire can result. Engine compartment fires can spread to the passenger compartment and cause injury to occupants.

To greatly reduce the possibility of this condition occurring, all vehicles will have changes made in their underhood environment. Specifically, all vehicles will have a manifold deflector installed, a minor change to decklid sealing, a PCV system modification and a general inspection (and repair as necessary) of underhood fluid and wiring systems. Additionally 1985-86 model year vehicles will have a new exhaust manifold installed to bring them up to 1987-88 specifications.

VEHICLES INVOLVED:

Involved are 1985-88 Pontiac Fiero model vehicles with 2.8L V6 engine (RPO L44) produced within the following VIN breakpoints:

SERVICE PROCEDURE:

To reduce the effects of fluid leaks which may lead to engine compartment fires, GM dealers will do the following at no charge:

1. INSTALL EXHAUST MANIFOLD DEFLECTOR

a. Remove outboard grille panels, and disconnect BOTH positive and negative battery cables (remove the battery on vehicles equipped with air conditioning).

b. Remove rear engine compartment lid. Remove rubber dust seal and retaining clips from leading edge (front) of decklid assembly (and leave off) (ILLUSTRATION C).

c. Remove air intake duct assembly (ILLUSTRATION D & E). Remove foam rubber seal on air cleaner housing neck (85-86 only). Remove PCV vent tube elbow(s), clamps and hoses at engine and air cleaner. DO NOT remove PCV vent tube mounted on forward engine compartment wall.

d. Apply penetrating oil to all bolts and studs of the forward exhaust manifold. THIS STEP IS VERY IMPORTANT TO AVOID STUD BREAKAGE-LATER ON.

e. Remove exhaust manifold to crossover bolts.

f. Disconnect upper engine strut.

9. Raise vehicle.

h. Remove converter down pipe to crossover bolts.

i. Remove converter heat shield.

j. Perform the following steps on air conditioned vehicles:

1. Remove air conditioning compressor shield. 2. Disconnect A/C belt and wires from compressor. 3. Remove A/C compressor mount bolts and lower A/C adjusting bracket. 4. Lower vehicle. 5. Remove upper A/C compressor mount bracket. 6. Raise vehicle.

k. Install jack stands under rear of vehicle to allow cradle to be lowered slightly.

l. Install jack stand under cradle and remove forward cradle bolts and nuts; lower cradle slowly approximately SIX (6) inches below mountings (for better access to front exhaust manifold). Do not lower more than SIX (6) inches.

m. Remove outer exhaust manifold heat shield.

n. Remove forward manifold bolts and studs. Best results will be obtain- ed by:

- Applying penetrating oil early (Step C) and reapply now.

-In the event of bolt breakage, a service tool for piloting easy-outs (WITHOUT removing the cylinder head) has been provided. Kent-Moore Tool J-38782 has been provided to all involved dealers.

o. Clean exhaust manifold gasket surfaces. Inspect 1987-88 exhaust manifold for any evidence of cracking or significant warpage. The 1985-86 vehicles will have a new (slotted flange) manifold installed if not already equipped.

p. Cut wire harness bracket off engine coolant pipe to avoid interference with new shield.

q. Stack manifold deflector, gasket and manifold over new bolts and install (position on head using top bolts) using torque values described in ILLUSTRATION A & B.

r. Modify (ILLUSTRATION F) and install outer manifold heat shield (dimensions for modification on illustration).

s. Reattach cradle and torque cradle bolts according to the applicable Fiero Service Manual procedure. Remove jack stands. Lower vehicle.

t. Install crossover to manifold bolts using torque values described in ILLUSTRATION A & B.

u. Install upper A/C compressor mount bracket.

v. Install side heat shield (A/C equipped vehicles), and install battery (to be connected later).

w. Raise vehicle.

x. Install A/C compressor, attach wires, lower adjusting bracket and belt (do adjustment at this time).

y. Install converter down pipe to crossover bolts (installing new seal provided in the kit).

z. Install A/C compressor heat shield (A/C equipped vehicles), converter heat shield.

NOTE: THE STEPS BELOW ARE INSPECTION ITEMS. IT IS IMPERATIVE THAT CARE BE EXERCISED IN INSPECTION. THE PARTICULAR ITEMS HAVE BEEN CHOSEN DUE TO THEIR POTENTIAL ASSOCIATION WITH UNDERHOOD FIRE. SEE THE NOTES ON EACH STEP FOR THE TYPES OF REPAIRS AUTHORIZED.

PLEASE NOTIFY YOUR CUSTOMER OF ANY ISSUES NOT FIXED IN YOUR INSPECTION WHICH WILL BE HIS/HER RESPONSIBILITY.

ANY ISSUES NOT SPECIFICALLY AUTHORIZED IN THIS BULLETIN MAY BE DISCUSSED WITH YOUR APPROPRIATE BDC CONTACT PERSON WITH SERVICE RESPONSIBILITY.

aa. Conduct inspection underneath the vehicle for:

0 Any indication of transmission oil cooler hose leakage.

0 Interference between right-hand wheelhouse splash shield and coolant hose. IF CAMPAIGN 8Rl2 HAS NOT BEEN PERFORMED, DO IT NOW.

0 Any missing heat shield for this application (ILLUSTRATION G).

bb. Lower vehicle. Remove plug wire clip, slide conduit up, and reinstall clip, connect wires to spark plugs (ILLUSTRATION H). The clip is no longer seated on the bracket and should be repositioned above the edge of the rocker cover. Bracket should be removed.

cc. Loosen shift cable bracket bolt (already installed on manual transmission equipped vehicles; bolt supplied in kit for automatic transmission equipped vehicles).

dd. Install new PCV grommet in the forward rocker cover, new air intake duct (w/clamps) and vent tube/bracket assembly. Orient grommet with flat side facing forward (ILLUSTRATION I & J). Position tube/bracket assembly under shift cable bracket bolt (manual transmissions) or install bolt supplied kit (automatic transmissions). For 1987-88 vehicles, install rubber cap with clamp on air cleaner housing.

ee. Connect engine strut and torque according to the applicable Fiero Service Manual procedure.

ff. Install new oil filler cap on rear rocker cover.

gg. Inspect battery cable and routing for any signs of chafing or wear. Replace or reroute as necessary.

hh. Connect battery and install engine compartment side outer grill.

ii. Install J34730-1 (Fuel Pressure Gauge).

jj. Pressurize fuel system to approximately 40 psi by running fuel pump with key on. Using pressure gauge on schrader valve, monitor to check if system holds pressure. Observe coldstart and port injector connections at fuel rail as well as coupled fuel hose fittings for any sign of leakage. Repair as necessary.

kk. Pressurize HOT coolant system to 15 psi using a hand pump. Observe throttle body heater pipes at connection to throttle body for any signs of leakage. Repair any coolant leakage observed here or elsewhere within the engine compartment.

NOTE: STEP 2 IS AN INSPECTION ITEM. IT IS IMPERATIVE THAT CARE BE EXERCISED IN INSPECTION. THE PARTICULAR ITEMS HAVE BEEN CHOSEN DUE TO THEIR POTENTIAL ASSOCIATION WITH UNDERHOOD FIRE. SEE THE NOTES ON EACH STEP FOR THE TYPES OF REPAIRS AUTHORIZED.

PLEASE NOTIFY YOUR CUSTOMER OF ANY ISSUES NOT FIXED IN YOUR INSPECTION WHICH WILL BE HIS/HER RESPONSIBILITY.

ANY ISSUES NOT SPECIFICALLY AUTHORIZED IN THIS BULLETIN MAY BE DISCUSSED WITH YOUR APPROPRIATE BDC CONTACT PERSON WITH SERVICE RESPONSIBILITY.

2. INSPECTION

Conduct general inspection of vehicle for any other potential fire related issues, specifically:

- Rocker cover leakage from either gasket surface or PCV valve grommet leakage should be repaired if significant. SEEPAGE IS NOT SIGNIFICANT.

- Improper wiring harness, coolant hose, or fuel line routings which are resulting in chafing of a serious nature should be rerouted (and repaired if necessary).

- Inspect cooling fan operation (on 1985-87 the engine compartment blower fan also should be inspected). Replacement of relay, coolant switch, wiring or fan is authorized to make functional.

3. Install engine compartment lid.

4. Install Campaign Identification Label.

INSTALLATION OF CAMPAIGN IDENTIFICATION LABEL

Clean surface of radiator upper mounting panel and apply a Campaign Identification Label. Make sure the correct campaign number is inserted on the label. This will indicate that the campaign has been completed.
